With a bandage on his forehead ... and a bruise under his eye ... Washington Redskins lineman Trent Williams marched through the airport in Hawaii last night ... just days after being smashed in the head with a champagne bottle during a bar fight.

Williams -- 6'5", 318 lbs -- required 7 stitches to put his forehead back together after he was attacked in a Honolulu nightclub Friday night ... just days before he was supposed to play in the Pro Bowl.

The NFL decided to pull Williams from the game in the wake of the fight -- in which Williams was also shocked by a man with a stun gun.

The owner of the nightclub was arrested and charged with assault in connection to the attack on the NFL star. Williams has not been accused of any wrongdoing.

Badass Side Note -- according to reports, Williams is such a beast ... he DIDN'T GO DOWN even after he was bottled and tasered.
